Not a major project but I wanted to utilize the costume I had and the head from the 7. None of the bodies looked right to me so I used a slim with lengthened thighs and torso. I then padded the hips, stomach, arms and back. Stuck on some Lee hands and lengthened the neck connector of the head so it wouldn't be so short. Cut off the sleeves of the grey shirt so it wouldn't get too bulky around the neck and torso. He stands around 5'9" which is about the height of Downey. I think it makes the head look proportional to the body now.
I think I need a torch so I can use a harder solder. The pair I make now is just too fragile to handle. I would be replacing/ repairing too many to keep my sanity.
